Pythonaut trials with body armor.|
I use very big and thick welding gloves and skateboarder elbow protectors, cause at 65 I injure easily and recover slowly. But trike is not a bad idea. Has anybody tried to add suspension in the rear triangle (say 2 mountain bike style springs in each strut)?

Although I really admire the python riders,I gave up practicing anyway. I am riding my python trike for two years now. I like it much. I think the geometry of my trike is ok. I have gone through all different road surface and all weather. I climbed quit steep hills. The traction was enough. It is an enjoyment riding on ice because the surface is very smooth! Jinlin Wen 2009/10/29 Rhisiart Gwilym <Rhisiart@xxxxxxxxxxxxxx>Hi Pythonauts! This bruised and strained learner-rider needs a bit of advice. My learning-curve on my Python bike is going pretty much as other Pythonauts have described their first attempts to ride. But I have a small problem. It's called 'old age': Every time that I fall off, or when I'm pushing wildly with my stretched fingertips against the ground to prevent an imminent fall, I seem to bruise or strain something. (Can scarcely type this morning because of a strained right hand) I guess it doesn't happen so easily to younger, more elastic bodies. Nor do the resulting minor injuries take so long to get painless, then heal. ('I was that way once myself', he mused sadly....) So -- ruefully -- I think that I have to bring forward the trike back-end for my Python, which I planned to build anyway, as an alternate for the single-wheel back-end. As well as avoiding the slightly worrying build up of little bodily problems from trying to stay on my Python for more than thirty metres (the struggle is also AMAZINGLY hard work; I'm sweating and panting within a minute or two of starting a practice session) I'm also concerned that it's going to take me a long time to get fluent enough at riding the bike to be able to go on the road in traffic. But I want to be able to use my Python this Winter, rather than my conventional bike. I keep no car, and I ride right through the year, as my main form of personal transport, but I had a couple of near-miss worrying incidents last Winter with my standard bike on icy roads. Besides this, I've designed into my version of the Python front end provision to be able to put a minimal all-weather John-Tetz-style zote-foam fairing onto it, or a fitted spandex cape at least, so that I can ride in heavy rain. Done a few lash-up experiments with this already, and I'm pretty confident that it'll work, even in gusty cross-winds. So, everything seems to be pointing towards a trike set-up, at least until I'm fluent enough with my Python-steering reflexes. That leads me to ask for some advice: I notice that some trikes have their back wheels set behind the rider's seat, whilst some have them set well forward, almost level with the rider. So how does the placing of the back wheels affect the percentage of the overall weight carried by the front-wheel -- **and how, therefore, is the crucial traction on wet/steep/gravelly surfaces affected?** This is my key question. My Python, like my other bikes, will have to be a serious work-horse, able to carry freight, and able to handle any weather conditions and any surface, on or off road. I notice that Henk's trike is a serious load-carrier, and Wen's seems to be pretty good too, and snow-capable. Any advice/experience from other Pythonauts about the best way to design my trike back end for this spec. is very welcome. I should say too that, despite being in the thick of ironing out the wrinkles at the moment, I really LOVE this bike, even though I can't stay on it yet. I can see it becoming my number one personal transport rig hereafter. Once again: thanks and respect, Jurgen, for the trail-blazing. Plenty of times the past few days I might have thought: 'I've made a big mistake here. This bike isn't rideable,' if I didn't know -- from the videos and the listees' accounts of their early adventures -- that that's not so. With that vital knowledge, I persisted, and already I can see progress in staying balanced and moving forward. But bloody hell I'm all bruises and strains, even though I've been practising on short, soft turf.

Damn, that rider in the vid is good. Why can't I ride like that! Other related videos offered beside that one led me to this too: http://www.youtube.com/watch?v=659J7qLFquE&feature=related I've felt that I've been within an ace myself of getting that 'click' he mentions, in some of my most recent practice rides. Maybe I should persist with the bike set-up a little longer(my strained hand is better this morning)...... Many thanks for all the offered useful knowledge. I'm still wavering, though: should I go for the complete trike back end, or simply put a couple of stabilisers on my bike, just like a little child's first bike, and carry on trying to reach that click point? I'm tempted to say that I should stick with Wen and the other older Pythonauts. I'm only a year behind you, Wen, so -- SOLIDARITY BROTHER! But still, it would be nice to get to the breakthrough, and achieve that fluent ease of riding, like the young guy in the vid above, or like Jurgen doing eight-turns in that video on the Python website. Damn! What do I do......? Thanks again to all for the advice. Hwyl fawr, RhG ------------------------------ End of python Digest V7 #63 ***************************
